From Wikipedia, the free encyclopedia, we begin reading an article “The Ten Days of Repentance (Hebrew: עשרת ימי תשובה, Aseret Yemei Teshuva) are the first ten days of the Hebrew month of Tishrei, usually sometime in the month of September, beginning with the Jewish holiday of Rosh Hashanah and ending with the conclusion of Yom Kippur.”

The Jewish Virtual Library also has an article on this subject that begins with this:
“The ten days starting with Rosh Hashanah and ending with Yom Kippur are commonly known as the Days of Awe (Yamim Noraim) or the Days of Repentance. This is a time for serious introspection, a time to consider the sins of the previous year and repent before Yom Kippur.”

Rabbi Dr. Reuven Hammer, former President of the International Rabbinical Assembly, one of the founders of the Masorti Movement in Israel, and currently Head of the Masorti Beth Din in Israel has an article on the internet that starts out wih “The days in between Rosh Hashanah and Yom Kippur are an important component in the process of repentance.”
